- Abstract
<bold>Background: </bold>Management of fluid in the limbs is a challenge faced by people with disabilities. In prosthetics, a means for transtibial prosthesis users to stabilize their residual limb fluid volume during the day may improve socket fit.<bold>Objective: </bold>To determine if releasing the panels and locking pin of a cabled-panel adjustable socket during socket release significantly improved limb fluid volume recovery and retention over releasing the panels alone.<bold>Design: </bold>Repeated-measures experiment to assess the effects on limb fluid volume retention.<bold>Setting: </bold>Participants were tested in a laboratory setting while walking on a treadmill.<bold>Intervention: </bold>Release of a locking pin tether during sitting as a limb volume accommodation strategy.<bold>Main Outcome Measure: </bold>Percent limb fluid volume retention for panel and pin release compared with panel release alone at 2 minutes (short term) and 50 minutes (long term) after subsequent activity. Limb fluid volume was monitored using bioimpedance analysis.<bold>Results: </bold>Median percent limb fluid volume retention for the panel and pin release was significantly greater than panel release alone for both anterior and posterior regions for the long term (P = .0499 and .0096, respectively) but not the short term (P = .0712 and .1580, respectively).<bold>Conclusion: </bold>Augmenting panel release with pin release may be an effective accommodation strategy for prosthesis users with transtibial amputation to better retain limb fluid volume.
